673895 ÷ 78 
Our goal is to divide 673895 by 78.

Step 1:
78 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 78

Advancing to step 2:
78 can be fit into 67 0 times, resulting in a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Include the next digit (3) from the dividend after 67, then repeat: 673 / 78

Advancing to step 3:
78 can be fit into 673 8 times, resulting in a remainder of 49.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 624 from 673 to get 49.
Fetch the next digit (8) from the dividend, attach it to 49 and continue: 498 / 78

Step 4:
498 divided by 78 is 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 86.0
Deduct 468 from 498 and we're left with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 78

Moving on to step 5:
The number 78 fits into 309 3 times, leaving a remainder of 75.
The next digit of our result is 3. 
Result so far: 863.0
If we take 234 away from 309, we end up with 75.
Take the next digit (5) from the dividend and append it to 75, then repeat: 755 / 78

Advancing to step 6:
755 divided by 78 is 9 with a remainder of 53.
The number 9 becomes the next digit in our result. 
Result so far: 8639.0
If we take 702 away from 755, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 7:
If we divide 530 by 78, we get 6 and a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 8639.6
Subtracting 468 from 530 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 8:
78 can be fit into 620 7 times, resulting in a remainder of 74.
The next digit of our result is 7. 
Result so far: 8639.67
If we subtract 546 from 620, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 9:
740 divided by 78 is 9 with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 8639.679
Subtract 702 from 740 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
The number 78 fits into 380 4 times, leaving a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 8639.6794
If we take 312 away from 380, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 11:
If we divide 680 by 78, we get 8 and a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 8639.67948
The remainder is 56 after subtracting 624 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
78 goes into 560 7 times with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 8639.679487
If we take 546 away from 560, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
78 can be fit into 140 1 times, resulting in a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 8639.6794871
Subtract 78 from 140 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 14:
78 can be fit into 620 7 times, resulting in a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 8639.67948717
If we subtract 546 from 620, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final result is 8639.67948717 with a remainder of 7.4e-08.
